Scientists discover Greenland sharks can see for centuries, debunking blindness myth

 Recent studies reveal that Greenland sharks possess well-preserved visual systems that can last for centuries, challenging the previous notion that they were nearly blind. Research shows that their eyes are uniquely suited for low-light environments, demonstrating impressive adaptability. Scientists found healthy rod cells and active genes responsible for light detection, indicating these sharks have a remarkable ability to maintain their eyesight throughout their extended lifespans. Recent studies reveal that Greenland sharks possess well-preserved visual systems that can last for centuries, challenging the previous notion that they were nearly blind.
